ok this is how it is at my school...if its in your locker, then they can search ONLY the locker, unless your bag is open and they can see inside. And they cannot search the cars unless something is in visible site without getting in the car. (unless they get an "annonymous" tip or something along those lines)

Actually, my friend was suspended last year because a teacher found out he had bud, so he threw it in some locker, but a teacher saw him do it...he should of just hid it in his back pack.
